PEDAI...

SPECIFICATION forming part of Letters Patent No. 364,865, dated June 14, 1887.

Application filed April 11, 1887.

To aZZ whom'it may concern:

Be it known that we, HENRY SOHWESINGER and J osnrrr CoURvILLE, of Detroit, county of useful improvements in organ-pedals, as more fully hereinafter described, and more particularly pointed out in the claims.

In the drawings which accompany this application, Figure 1 is a vertical cross-section of a portion of an organ illustrating our invention,with parts in elevation. Fig. 2 is a vertical section across the treadle. Figs. 3 and 4. are separate views illustrating the method of engaging the webbing at its two ends. Fig. 5 illustrates the method of engaging the forward end of the treadle with the base of the organ-case.

To carry out our invention as follows:

A represents the organ-case; A, its base.

13 represents the treadle. The engagement of the forward end of the treadle with the base of the organ-ease constitutes one feature of our invention, and consists, essentially, ofproviding the organ-case with a rod or loop, 0, having its ends engaged into the said base of the organ-case, that portion of the rod or loop intermediate of its ends being raised above the surface of the base to permit the engagement therewith of hooks b I), engaged in the end of the treadle, as shown. surface of the said base might be grooved to permit the engagement of the said hooks with said rod or loop, if desired, the rod or loop having contact with the surface of the base. It is evident that as so constructed the outer end of the treadle is very readily engaged in place upon the base of the organ-case, the said construction and arrangement also permitting the treadle to flex readily at this point.

The treadle is provided with moldings B B upon its edges, and a covering of fabric, B.

Of course the upper Serial No. 234,413. (No modeLl The molding is preferably constructed with upper flanges, 1) b to embrace said fabric be tween them and the body of the treadlc, thereby holding the fabric firmly in place and permitting-its ready renewal by disengaging the molding, which may be tacked in place.

' D is the pedal-arm having a pivotal engagement at its base with the treadle, this engagement being effected by inserting a pivot or pin, d, from one side of the body of the treadle through the lower end of said arm before the adjacent molding is secured in place. When said molding is secured in place, the pivotal connection is effectually hidden from view.

E represents the webbing, said webbing engaged at its lower end with the pedal-arm in the following manner: Said arm is provided with a movable clasp, D, constructed of a suitable piece of wire, bent at its ends to engage in a groove, d, in the rear face of said arm, said clasp extending across the front face of said arm at its upper end. Being thus engaged upon the arm, itits evident that the portion of the clasp which extends across the front face of said arm is capable of an upward and downward movement.

The clasp is so constructed as to permitthe engagement of the lower end of the webbing between it and the frontface of said arm, said webbing being turned under, as shown at 6, its end thus engaged between the clasp and the front face of said arm, when, as will be observed, the pull upon the webbing will cause the clasp to bind the end of the webbing between it and the face of the arm, and so pre vent its ready or accidental disengagement. The firmerthe pull upon the webbing the more firm is the grip of the clasp to bind the end of the webbing upon the arm.

The Webbing extends over an ordinary roller or pulley, F, engaged upon the organcase. A similar clasp to that already described engages the upper end of said webbing upon the eXhausterG of the bellows, said exhauster being preferably provided with a block or shoulder, g, slotted upon its upper face, as shown at g, to receive a clasp, G,constructed in the same manner as the clasp D.

The upper end of the webbing is engaged be tween the clasp and the under face of said block or shoulder, as shown at c; and it is evident that a pull upon the webbing draws the clasp slightly forward, causing the, clasp to hug the webbing tightly between itself and said shoulder or block and prevent its disengagement. H represents the usual retractingspring to close the exhauster when pressure is relieved from the pedal.

It is obvious that such a construction and arrangement for uniting the forward end of the treadle upon the organ-case is simple and economical, as is also the method of pivoting the pedalarm upon the treadle, the engagement of the fabric in place beneath the flanges of the molding, while at the same time the method and arrangement of clasping the two ends of the webbing upon the pedal-arm and valve, respectively, are also very simple and economical.

Heretofore, where the webbing has usually been tacked on at its ends to the adjacent parts, in case ithas been necessary to renew the webbing, it has been found that the adjacent parts have been frequently split or damaged, so as to make it diilieult to renew the webbing and make a neat and satisfactory job. By our invention, however, the webbing may be renewed at any time when desired with the greatest facility,while the parts to which our improved clasps are attached are unmarred and are not damaged, as hasbeen the case heretofore. The end of the webbing may be tacked upon the edge of thepart g, as shownin Fig. 4-, ifdesired.

1. The combination, with an organ'easc and its treadle, of a loop or red, O, engaged at its end with the organ-ease, said treadle provided with hooks b b,engaged with said rod or loop, substantially as described.

2. The combination, with an organ-treadle, of a pedal-arm, a pivot inserted through one side of said treadle through the lower end of said arm, the edges of said treadle provided with moldings, substantially as described.

3. The combination, with a treadle, of a pedalnrm, a pivot passed from one side of the treadle through thelower end of said arm, a fabric covering the said treadle, and moldings engaged upon the sides of said treadle tohold said fabric in place thereon, substantially as described.

4. In an organ'pedal, the combinatiomwith the pedal-arm and the exhanster G, of a "webbing uniting said arm and exhauster, said webbing engaged at its ends upon said arm and exhauster, respectively, by clasps Dand. Gr, substantially as and in the manner de scribed.

In testimony whereof we sign this SPCClfHflP tion in the presence of two witnesses.
